Arithmetic operations in Python 2.7

 Some basic arithmetic operations in Python 2.7

 Addition
>>> 7+14
21

Subtraction
>>> 14-7
7

Multiplication
>>> 7*14
98

Division
>>> 14/7
2

Floor division
>>> 15//7
2

Exponent
>>> 7**2
49

Working with equations
>>> x=7
>>> y = 14
>>> x*y
98

>>> x=7
>>> y=14
>>> z=x*y
>>> print z
98

>>> x=14
>>> y=7
>>> z=(x+y)*x
>>> z
294

Comparison operations in Python 2.7
>>> 7==7
True

>>> 7==14
False

>>> 7<7
False

>>> 7<14
True

>>> 14>7
True

>>> 7<14>6
True

I believe I covered most of the arithmetic operations in Python 2.7. I am providing only examples because I believe it's the best way to learn. You will notice that I am giving very basic examples. This is because I want you to advance slowly and to start loving programming in Python.
Python is widely spread programming language used in many branches and from thousands of programmers. Earning potential with Python is unlimited. You can apply for projects everywhere. you can even create the projects and starting earning thousands of dollars.

Feel free to contact me if you have any questions.

Python 2.7 Basic Examples

Python is very progressive programming language. It's widely used in many areas.

In this blog post of "Python tutorials" I post some basic examples that will help you to get some basic knowledge and understand Python syntax. These examples are for Python 2.7 version.


Simple use of print command

>>> print 'I am wealthy'
I am wealthy

Use of print command with 'a' variable

>>> a = 'I am wealthy'
>>> print a
I am wealthy

Join two variables with text in one sentence and print it

>>> a = 'I am'
>>> b = 'wealthy'
>>> print a + ' ' + b
I am wealthy

Multiply 'a' variable that contain text

>>> a = 'I am wealthy'
>>> print a*5
I am wealthyI am wealthyI am wealthyI am wealthyI am wealthy

Print more words at once

>>> print 'wealth', 'health', 'forgiveness'
wealth health forgiveness


Using '\' to separate two words with empty place

>>> print 'wealth\thealth'
wealth        health

Using '\n' to separate two words in two rows

>>> print 'wealth\nhealth'
wealth
health

Print a sentence that contain '

>>> print 'it\'s good to forgive'
it's good to forgive

Print a sentence that contain '

>>> 'it\'s good to forgive'
"it's good to forgive"

Print sentence surrounded by '

>>> print '\'I am wealthy\''
'I am wealthy'

Check if a word starts with certain alphabet/s

>>> 'wealth' .startswith('w')
True

>>> 'wealth' .startswith('n')
False

>>> 'wealth' .startswith('weal')
True

Check if a word ends with certain alphabet/s

>>> 'wealth' .endswith('h')
True

>>> 'wealth' .endswith('l')
False

>>> 'eal' in 'wealth'
True

>>> 'l' in 'health'
True

Check how many time some alphabet/s are in a sentence or words

>>> 'wealth health forgive good love humble smart'.count('h')
4

>>> 'wealth health forgive good love humble smart'.count('wealth')
1

Convert lower alphabets to upper

>>> 'wealth'.upper()
'WEALTH'

Convert upper alphabets to lower

>>> 'WEALTH'.lower()
'wealth'

Capitalize first alphabet in a word

>>> 'wealth'.capitalize()
'Wealth'

Capitalize each first alphabet in a list of words

>>> 'wealth health good'.title()
'Wealth Health Good'

Replace alphabet/s or word/s with others

>>> a = 'I am wealthy'
>>> a.replace('wealthy', 'healthy')
'I am healthy'

Replace empty spaces

>>> a = 'wealth health goodness forgiveness love'
>>> a.replace(' ', '')
'wealthhealthgoodnessforgivenesslove'

Other way to replace word/s
>>> a.replace('love', 'I').replace('good', 'forgive')
'I forgive'
